Swollen, Itchy Eyelid

About eight months ago, the inner corner of my right upper eyelid was itching, and then it started swelling. I didn't use anything and after a few days, the swelling went down but left the area very dark. Recently, this itching and swelling has reoccurred and I don't know what to do.

I would suggest that you see an ophthalmologist. The signs and symptoms presented may represent a contact dermatitis or other condition, however, an examination is needed to fully evaluate your concern.
